When you want to connect your PTZ camera to your DVR, you need to know how to identify the physical connectors. Then, you will want to wire them correctly and set up the devices using the RS-485 standard as well as the correct protocol. Continue reading to learn how to connect your PTZ camera to your DVR and what to do when you have multiple cameras.
How to Connect Your PTZ Camera to Your DVR
There are certain basic steps that you can follow to connect your PTZ camera to your DVR. Take a look at the following steps.
First, you need to find and identify the physical RS-485 connector in your PTZ camera. Locate the physical RS-485 connector in the DVR, and then run your wire between the two. When you use this RS-485 standard and twisted pair cables, you will be able to send commands to your camera as far as 3,937 feet away, and you can use more than one camera in a serial line.
Once you have the wiring done, you can set the dip-switches on the camera. This allows you to choose the parameters. You need to log into the DVR so that you can set up the parameters for your PTZ camera.
It is important for the camera and the DVR to have a common protocol, such as Pelco P or D. This is a communication protocol made for PTZ cameras. If your PTZ camera and your DVR are manufactured by the same company, they will have the same protocol, so you don’t need to add a Pelco. However, if they don’t, you can add a Pelco P or D to make sure that they can communicate.
How Many PTZ Cameras Can You Connect to a DVR?
You can connect multiple PTZ cameras to a DVR. This is a process where you will take a number of cameras and connect them so that they use the same joystick. You can connect one, two, or multiple PTZ cameras. If you are using the cameras for surveillance of different parts of a building, you might want to use more than one camera.
You can connect the cameras individually or you can daisy chain them. If you set up more than one camera, you will need a PTZ block that can take more than one 2-lead RS485 wires from the cameras to communicate with the single connection found on the back of security camera recorders. You need the PTZ block if you plan to connect more than one camera to a DVR because you can only connect one pair of RS485 leads to the back of the DVR. The connection is really important because the cameras cannot receive commands from the DVR if they aren’t hooked up properly.
How to Connect 2 PTZ Cameras to a DVR
If you want to connect 2 PTZ cameras to your DVR, you will need a PTZ block that allows multiple 2-lead wires from the PTZ cameras because you can only connect one set of RS485 wires to your DVR. Once you connect them, you will need to configure the RS485 settings on your DVR.
How to Connect Multiple PTZ Cameras to a DVR
If you plan to connect multiple PTZ cameras to your DVR, you can either connect them through a PTZ block or you can daisy chain them. You can only daisy chain analog PTZ cameras, but IP cameras can use POE switches for a similar effect. You can daisy chain up to 32 analog PTZ cameras up to 4,000 feet.
There are three cables for power, video, and data. You need to make sure that your DVR and all of the cameras are set to the same protocol. Your manual should tell you how to do this. You will want to assign a distinct ID to each camera using the DIP switch, and you will assign termination to the last camera on the chain. To do this, you can turn it off on all but the final camera.
When you want to connect PTZ cameras to your DVR, you should use the RS485 connection. You can connect more than one. You can use a PTZ block, or you can daisy chain multiple cameras. Make sure that the cameras and the DVR have the same protocol so that they can communicate with each other. It is important because they won’t work if they aren’t connected properly.
